13. The Massacre Chapter - Part 8 - Finale

One after another, Rika's friends are killed while trying to protect her. Takano dissects Rika, but does so without anesthesia, as requested by the latter in an attempt to carve the identity of the culprit behind all the Hinamizawa murders in her mind and prevent the events from this and past worlds from repeating themselves. The villagers are rounded up at the school and gassed to death, while an ecstatic Takano proclaims her ascension to godhood.
